ABSTRACT:
An automated hole inspection system for measuring, on a plurality of planes, the diameter of a hole in a workpiece includes a hole gauge for measurement of a hole diameter in one plane, and a remote centering compliance device connected to the proximal end of the probe for allowing the probe to move laterally, perpendicularly to the probe axis, to self-center in the hole. A center locking device locks the remote centering compliance device on the axis of the probe after the probe has self-centered in the hole. A rotary actuator rotates the remote centering compliance device to rotate the probe to a new desired plane for making an additional diameter measurement in the hole.
